[0030] By placing the end of the connecting line not drawn in the middle of the connecting band 1, folding the end of the connecting band 1 with the button 3 towards the connecting line and buckling the button 3 with the appropriate button hole 2, the end of the connecting line is limited; at the same time, according to the diameter of the other end of the connecting line, the adjusting assembly 9 can be adjusted to adapt the space inside the limiting ring 4 to the diameter of the other end of the connecting line, and the other end of the connecting line is clamped into the limiting ring 4.

[0031] In addition, the outer wall of the outer ring of the annular chamber 5 is fixedly connected with a plurality of first teeth 7, and the plurality of first teeth 7 are distributed at equal intervals; the equal interval arrangement of the plurality of first teeth 7 forms an accommodating space between adjacent two first teeth 7, which is convenient for limiting the second tooth 11, thereby limiting the movable ring plate 10.

[0032] In addition, the inner ring of the limiting ring 4 is provided with four hole expansions 8 which are in communication with the annular chamber 5, and the four hole expansions 8 are arranged in an annular array about the center of the limiting ring 4; the hole expansion 8 can limit and guide the movable rod 12.

[0033] In addition, the adjusting assembly 9 comprises a movable ring plate 10 which is slidingly connected between the upper and lower slides 6, the outer ring of the movable ring plate 10 is fixedly connected with a plurality of second teeth 11, the inner ring of the movable ring plate 10 is hingedly connected with four movable rods 12, the ends of the four movable rods 12 away from the movable ring plate 10 slidingly penetrate the corresponding hole expansion 8 and extend to the outside and are fixedly connected with a pressing plate 13; wherein the movable ring plate 10 is made of hard plastic, so that it has a certain hardness and toughness and can be deformed under external force; by pulling the movable ring plate 10, the movable ring plate 10 can slide outwardly in the slide 6 while driving the second tooth 11 on it to extrude and rub with the first tooth 7, and a clear jerk can be felt, at the same time, the movable ring plate 10 drives the end of the movable rod 12 to move through the hinge point, so that the middle part of the movable rod 12 slides outwardly in the hole expansion 8 and swings by a certain angle, thereby driving the pressing plate 13 to move towards the opening of the limiting ring 4, so that the space between the pressing plate 13 and the other end of the connecting line is adapted.

[0034] In addition, the left end of the movable ring plate 10 is fixedly connected with a stop block 14, and the outer middle part of the stop block 14 is fixedly connected with a push plate 15; by pushing and pulling the push plate 15, the movable ring plate 10 can be driven to move in the slide 6 through the stop block 14; the stop block 14 is made of hard plastic, and the stop block 14 and the right end of the limiting ring 4 can be opened by a certain angle, which is convenient for the other end of the connecting line to enter.

[0035] In addition, the plurality of second teeth 11 are distributed at equal intervals, the material of the second teeth 11 and the material of the first teeth 7 are both made of elastic plastic, the second teeth 11 and the first teeth 7 are staggered and engaged, so that when the movable ring plate 10 is pulled, the first teeth 7 and the second teeth 11 can be mutually rubbed and extruded, and a certain deformation occurs, thereby facilitating the position limiting of the movable ring plate 10; the material of the extrusion plate 13 is rubber, and the diameter of the movable rod 12 is smaller than the inner diameter of the expansion hole 8, so that a gap is left, the extrusion plate 13 made of rubber can be deformed to cooperate with the movable rod 12, thereby facilitating the movement of the movable rod 12 in the expansion hole 8.

[0036] When in use, one end of the connecting line not shown is placed in the middle of the connecting band 1, one end of the connecting band 1 with the button 3 is folded towards the connecting line and the button 3 is buckled with the appropriate button hole 2, so that one end of the connecting line is limited; at the same time, the adjusting assembly 9 can be adjusted according to the diameter of the other end of the connecting line, when the diameter of the other end of the connecting line is small, the other end of the connecting line can be placed in the inside of the limiting ring 4 first, then the push plate 15 is pulled, the push plate 15 can drive the movable ring plate 10 to move outward in the slide 6, the movable ring plate 10 can drive the second teeth 11 on it to extrude and rub with the first teeth 7, and a clear jerk can be felt, at the same time, the movable ring plate 10 drives one end of the movable rod 12 to move through the hinge point, so that the middle part of the movable rod 12 slides outward in the expansion hole 8 and swings by a certain angle, thereby driving the four movable rods 12, so that the extrusion plate 13 can move towards the opening of the limiting ring 4, until the extrusion plate 13 and the stop block 14 contact with the other end of the connecting line.

[0037] When the other end of the connecting line is large, the stop block 14 can be pushed by the push plate 15 first, so that the stop block 14 drives the movable ring plate 10 to move inward on the slide 6, so that the above process moves in the opposite direction, so that the extrusion plate 13 approaches the inner wall of the limiting ring 4, thereby increasing the distance between the extrusion plate 13 and the opening of the limiting ring 4, until the distance between the right end of the limiting ring 4 and the stop block 14 is slightly smaller than the diameter of the other end of the connecting line, then the stop block 14 is gently pried outward to deform, so that the other end of the connecting line passes through and enters the limiting ring 4, then the stop block 14 is released, and the stop block 14 restores and cooperates with the limiting ring 4 and the extrusion plate 13 to firmly limit the other end of the connecting line.

[0038] All the technical features in the embodiment can be freely combined according to actual needs.
